-
(Texas A&M University. Libraries, 1985)Field and greenhouse studies were conducted at College Station, Texas to investigate the interrelationships between biological N2 fixation and seed yield in cowpea [Vigna unguiculata (L.) Walp.]. Seed yield of inoculated ...
-
(Texas A&M University. Libraries, 1980)Two low molecular weight peptides, each with a molecular weight of about 5.000, were isolated from soybean nodules. The levels of these peptides were positively correlated with the level of nitrogenase activity. These ...
-
(Texas A&M University. Libraries, 1976)A series of substituted divinylsilanes: dimethyl-distyryl-(11). Triphenyl-stryrl-(12), diphenyl-distyryl(13), have been prepared for photochemical study. The results of low conversion photolyses of the di-methyl-di-styrylsilane ...
-
(2016-07-28)Chemical process design requires mathematical models for predicting thermophysical properties. Those models, called equations of state (EoS), need experimental data for parameter estimation and validation. This work presents ...
-
(2023-04-12)This research aims to develop foam chelates to facilitate their distribution over target zones to improve mobility control. The use of a conventional acid cannot produce acceptable stimulation results because of major ...
-
(Texas A&M University. Libraries, 1983)Nitrogen is the nutrient that most frequently limits growth of grasses in rangelands. Symbiotic nitrogen fixation through establishment of legume-grass mixtures is a means of providing N inputs to rangeland systems. Siratro ...
-
(2023-07-12)There is growing importance in developing more sustainable agronomic management strategies and enhancing resource use efficiency in warm-season turfgrass systems. Two multi-year field studies were conducted in College ...
-
(2015-08-13)Nitrogen, phosphorous and carbon are naturally occurring nutrients that are essential for all organic life. However, the water quality of many water bodies is negatively affected by high concentrations of these nutrients. ...
-
(Texas A&M University, 2004-09-30)Concerns over water quality have led to required removal of 50 % of dairy manure phosphorus (P) from the impaired Bosque River Watershed. Application of composted dairy manure (CDM) to sod and moving P off the watershed ...
-
(Texas A&M University. Libraries, 1989)Densities of five mixtures of carbon dioxide + nitrogen (x[CO2] = 0.10560, 0.25147, 0.50365, 0.71105, 0.90921) and pure nitrogen were measured at 300 and 320 K at pressures to 10 MPa using the Burnett technique. Second and ...
-
(Texas A&M University, 2005-02-17)Regulations for total maximum daily loads require management of phosphorus loading from farms and municipalities. This study evaluated environmental impacts of a system for using and exporting the phosphorus in composted ...
-
(2021-12-09)The ruminal microorganisms are an excellent example of how the body adapts to different feeding sources on its own initiative. The ruminants, in contrast to monogastric creatures such as chickens, create an ideal environment ...
-
(2009-05-15)The work presented in this dissertation focuses on + 4 NH in marine sediments and attempts to elucidate some of the specific pathways and processes affecting + 4 NH in coastal marine regions. The majority of work was ...
-
(Texas A&M University. Libraries, 1985)Arrowleaf clover (Trifolium vesiculosum Savi) and ryegrass (Lolium multiflorum Lam.) are commonly grown together but the fertilizer N needs of these plants when grown in mixture are not well understood. Two greenhouse and ...
-
(2020-05-20)Prokaryotes make up the majority of the biomass in sediment, where they play a role in cycling organic carbon and regulate the fluctuation of organic matter. Studies of abundance, genomic composition, and ecological roles ...
-
(1994)When grown in the absence of combined nitrogen, the photosynthetic cyanobacterium Anabaena sp. strain PCC 7120 fixes nitrogen inside terminally differentiated cells called heterocysts. Differentiation is a complex process ...
-
(Texas A&M University, 2005-02-17)The Upper North Bosque River (UNBR) watershed is under a Total Maximum Daily Load (TMDL) mandate to reduce Phosphorus (P) due to excess nutrients in the watershed. To address these problems, Texas A&M University researchers ...
